In order to solve the problem of vehicle sample collection difficulty,this paper proposed a method of automatic data collection of vehicle samples on the basis of vehicle detection and tracking.Firstly,the Blob analysis technology was employed to detect vehicles from video.Secondly,moving vehicles were tracked by the Blob method and CamShift tracking algorithm.Again,after analyzing the movement of vehicles,the vehicle states of movement and stop were detected.Finally,the detail image obtained by controlling camera pan was used as the vehicle samples.Experimental results show that the proposed method is of high real-time performance and accuracy in detecting and tracking of vehicles and the judgment of vehicles states.Meanwhile,the obtained vehicle sample images with rich details was able to meet the basic requirements of vehicle sample library construction.
